Patent CA-2280385-A1 (CA)
Title: Control arrangement and method for high-speed source-transfer switching system
Inventor: O'LEARY RAYMOND P
IPC: H03K17/13
Filed: 1999-08-16
Abstract: A control arrangement and method is provided for a power electronic system configured as a high-speed source-transfer switching systems (HSSTSS). The HSSTSS supplies an electrical load with alternating current from either a first source or a second source via respective first and second solid-state switches. The control arrangement avoids undesirable current flow between sources via a comparison of the voltages of the sources and current in the outgoing source, i.e. a polarity comparison to ensure that the current that will flow in the incoming source after transfer will be in opposition to the current flowing in the outgoing source before transfer. Thus, the transfer is delayed until the polarity comparison is satisfied. Additionally, the control arrangement minimizes undesirable transfer delays by establishing appropriate transfer conditions before issuing control signals to perform the transfer between sources.

Title: Process for the treatment of arsenic-containing sludge
Inventor: SUGITA SATORU
IPC: C02F11/145
Filed: 2000-02-10
Abstract: The present invention relates to a process for the treatment of arsenic-containing sludge obtained by adjusting arsenic-containing waste water to a PH of 12 or greater by the addition of a calcium compound and subjecting the waste water to solid-liquid separation, the process comprising the steps of adding a calcium compound to the arsenic-containing sludge slurry obtained by the solid-liquid separation, dewatering the resulting sludge, drying the dewatered sludge, and calcining the dried sludge. According to the present invention, arsenic-containing sludge obtained by treating waste water to precipitate arsenic present therein can be calcined to yield a calcined product which involves no risk of arsenic redissolution when it is dumped. Moreover, there is no possibility that arsenic compounds may be volatilized during calcination.

Abstract: An electrical pressure sensing switch for a pressure cooker comprises a plunger slidably and sealingly mounted in a lid 21 of a cooking vessel 20. The plunger 24 is moved towards one end of a pivoted lever 33 when pressure rises inside the vessel 20. The other end of the lever is positioned to press down against an operating arm 26. When the force applied by the plunger as a result of higher pressures in the vessel 20 is sufficient to overcome bias of a spring 28, the arm 26 is moved down by the lever. This results in operation of micro-switches 31 and 32. Embodiments of the invention are mechanically simple and accommodate wide tolerances without loss of calibration, while necessary electrical parts are separated or separable from the lid 21 to facilitate cleaning and washing.
